Buying cannabis seeds online in South Dakota: the federal rules

Under the federal law in force today (the 2018 Farm Bill), cannabis seeds with no more than 0.3% delta-9 THC have been treated as hemp, as the DEA said in informal letters in 2022. A new federal hemp definition takes effect on December 11, 2026, unless Congress delays it again, and it excludes viable seeds from plants above 0.3% total THC. Regulators have not yet said how they will apply it to seeds. Once a seed germinates, state law decides whether you may grow it. Read the federal section of our US guide.

Growing season and climate in South Dakota

For patients who may grow, South Dakota's outdoor season is short and continental, with frost possible into May and again by late September in many years. East River is a little more humid with better soils, while West River is drier, windier and prone to hailstorms. The Black Hills sit higher and cool off sooner, shortening the season further. Plants that finish by mid September or autoflower are the safer choice.

Two mid-September finishers and a compact autoflower fit a plains season that can close with frost before October.

Harvest dates and THC figures are ranges from our strain pages, not promises: results depend on the grower, the method and the season’s weather.
